-v IMPROVEMENT m MnTAnmc canrnmens.

' Specicaton forming part of Letters Patent No. 42,815, dated' May 17, 1864.

Toall whom it may concern Be 'it known that I, CORNELIUS J. BERGEN,- of- Brooklyn, in the county of Kings .and

-State ot' New York, have invented andmadev a certain new and useful Improvcmentin Cartridges for Fire-Arms; and l do hereby declare'the following to be a fulll'clear, and exactdescription of the said Y- invention, referencebeing had to the annexed drawing, maksent the parts-more clearly; and similar marks of reference denote the same parts, y

Cartridges have heretofore been made with a percussion-pill at the rearr base of thc ball, to ignite the powder at the front end,a1'1dl `varions devices, such as projecting tn'bes'or tiges, have been employed tozignite the powder at the front end immediately .in the rear of the ball, in order that the effective force of i the gunpowder may be obtainedv by the powder burningback toward the breech while in a consolidated state, instead of being scattered in the barrel, as the ball progresses, inconsequencc of the ignition taking piace contiguous to the breech.

The nature of my said inventionV consists Yin a double metallic cartridge-casccontaining a channel or channels extending frolnthe fulminating material to the front portionof the powder near the base of the ball, whereby the metallic breech-loading cartridge isadaptedto the ignition of the powder at this lpoint,

producing the advantageous action of the powder above named. f

In the drawing, ya, is the ordinary metallic cartridge-case, of any. suitable size or shape,

yreceiving the ball b. 'c is .the ange' 'containing the 'fulminating material; but it. will be evident'that 'this fulminating material might be contained '.in'a teat or nipple, orv applied 'in any other convenient way 'to the cartridge. dis a metallic cylinder, closed at the rear end, formed with creases or groovesA 1 lengthwise ot' its sides, (one or more such grooves may be employed,) forming a channel between the two cases for conveying the. {iame fromthe fulminate to the base of the ball, at which point said channel terminates with an opening,

through whichthe lire reaches the powder.

Said opening may be formed by a n'otch in the case or cylinder d, or said cylinder may stop sufficiently short of the base-of the ball to leave the necessary opening.

What I claim,J and desire to secure by Letters Patent, is-) A double metallic'cartridge-case, 'provided with a channel or channels extending from lthe fulminating Amaterial to the front portieri` of the powder, substantially as specified.

In witness whereof I have hereunto set my signature ythis 26th day`of January,y A. D."
